Title: Method for treating organic polluted water containing phosphorus
Inventor: KATAOKA KATSUYUKI
IPC: C02F1/52
Filed: 2000-11-09
Abstract: PROBLEM TO BE SOLVED: To provide a treatment method by which phosphorus is removed from organic polluted water containing phosphorus so as to recover the phosphorus as a resource, production of excess sludge can be decreased to substantially zero amount, and moreover, the use amount of an aluminum-based phosphorus removing agent can be decreased. SOLUTION: In the biological treatment of organic polluted water containing phosphorus, an aluminum-based phosphorus removing agent is added to make the phosphorus insoluble and to precipitate the insoluble phosphorus with activated sludge. Then an alkali agent is added to the precipitated sludge to elute phosphorus from the sludge as well as to make the activated sludge soluble. Then the solid content is separated from the liquid and the separated sludge is supplied to the above biological treatment process. Magnesium ion or calcium ion is added to the separated liquid to recover the eluted phosphorus as magnesium ammonium phosphate or calcium phosphate. Then the liquid from which the phosphorus is recovered is returned to the biological treatment process and reused for the removal of phosphorus.

Title: Steering control device
Inventor: TOHATA HIDEO
IPC: B62D113/00
Filed: 2000-11-16
Abstract: PROBLEM TO BE SOLVED: To obtain steering reaction corresponding to vehicle behavior over the whole vehicle speed area. SOLUTION: The steering reaction is calculated from the sum total of steering angle corresponding steering reaction corresponding to a steering angle, yaw rate corresponding steering reaction corresponding to a yaw rate and lateral acceleration corresponding steering reaction corresponding to lateral acceleration. Since the yaw rate corresponding steering reaction and the lateral acceleration corresponding steering reaction respectively linearly increase together with the yaw rate and the lateral acceleration, both the yaw rate dominant at low speed time and the lateral acceleration dominant at high speed time are reflected on the steering reaction as vehicle behavior input.  In the steering angle corresponding steering reaction, sufficient steering reaction is obtained by setting both the yaw rate and the lateral acceleration large in a small area of a small steering angle, and the yaw rate and the lateral acceleration are gradually reduced from a linearly increasing prescribed steering angle so that the continuity is imparted to the steering reaction, and a sense of incompatibility is wiped out. Gain is used for adjusting the distribution ratio of the yaw rate and the lateral acceleration at respective vehicle speeds.
